抄録

CaO and ZrO₂ co-substituted polycrystalline BaTi₂O₅, (Ba_1-xCa_x)(Ti_0.995Zr_0.005)₂O₅, (BCT₂Z), was prepared by arc melting and the dielectric properties were investigated by AC impedance spectroscopy. b-direction orientation was obtained at any composition. The lattice parameters of a-, b- and c-axes first increased until x = 0.003 and then slightly decreased with increasing CaO content up to x = 0.020. The maximum permittivity of polycrystalline BaTi₂O₅ showed the highest value of 6230 at x = 0.020. The T_c of polycrystalline BaTi₂O₅ slightly decreased from 750 to 716 K when CaO content was increased up to 0.020.
